If the population of males below poverty line in state A is 3000 and that in state E is 6000, then what is the ratio of the total population of state A and E? 
Options:
A) 3:4
B) 4:5
C) 1:2
D) 2:3
E) None of these
Solution:

Population of state A below poverty line = 3000 × \(\cfrac{5}{3}\) = 5000

∴ Total population of state A = \(\cfrac{5000}{12}\) × 100 and the population of state E below poverty line = 6000 × \(\cfrac{11}{2}\) = 11000

∴ Total population of state E = \(\cfrac{11000}{10}\) × 100

∴ required ratio = \(\cfrac{5}{12}\) × \(\cfrac{10}{11}\) = \(\cfrac{25}{66}\) = 25:66
